Foolish take
By reducing its position by more than 90%, Sarasin is implying a lack of conviction in Tetra Tech's future business. That may be related to headwinds created by a reduction in the size of government and added scrutiny on government contracts by the current administration.
The Department of Government Efficiency (DOGE) initiated an ongoing practice of cutting federal staffing and spending. Tetra Tech stock has tumbled by 30% over the last 12 months in that environment. The stock has recovered in recent months, though, with a jump of 16% since April.
That came as the company reported a strong fiscal third quarter, with earnings per share jumping 34% year over year. Sarasin looks to have taken advantage of those gains to nearly fully exit its position in Tetra Tech.
